The GRID® STK (Orange) and GRID® STK X (Black) are an innovation in hand-held foam rollers. Specifically designed with GRID® surface and AcuGRIP handles to roll, release and relieve minor aches and pains.

The GRID STK X foam roller is designed with proprietary density zones, with an extra-firm density than the standard GRID STK, to target tight muscles. The three dimensional surface has a variety of widths to replicate the feeling of a massage therapist's hands, promoting the flow of blood and oxygen to repair muscle damage. The convenient size is perfect for the gym, office or on-the-road. Use seated or standing to relieve minor aches and pains.
